Staying dry and comfortable on a ride is of the utmost importance and the 1.81 Sleeveless Base Layer's designer, David Millar, knows this. The microfiber construction of the base layer means it is as soft and light as it could possibly be. The base layer's hydrophilic outer layer wicks moisture off the skin and out to the jersey without absorbing any moisture along the way. The base layer is perfect when combined with the Chpt. /// Jersey. Contrary to the subdued colours of the jersey, the base layer is far more outlandish, in a similar way that gentlemen may choose a different inner lining to his suit to contrast with the outside. In tailoring, this is called a reveal; a flash of color occasionally glimpsed that shows there is more than first meets the eye. Or, as we brash Americans like to call it, a club shirt.
PLEASE NOTE: Castelli Chpt. /// sizes tops by suitjacket sizing instead of standard S/M/L/XL for a more precise fit. A size 40 is approximately a "L" in Castelli tops.
